Description
The HD75173 is a quadruple differential line receiver with three state outputs. It is designed to satisfy the requirements
of EIA standards RS-422A, RS-423A and several CCITT recommendations. Each receiver features an active high
enable and an active low enable common to all four receivers. It also features differential input sensitivity of 200 mV.

Notes: 1. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting
input
2. The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two
of which may be realized at the same time.

2. The algebraic convention is used in this data sheet for threshold voltage levels only.
3. Not more than one output should be shorted at a time.
4. Refer to EIA standards RS-422A and RS-423A for exact conditions.
